Experts say Metrolink CAN run on solar power
MANCHESTER’S hardly renowned for its sunny weather – but energy experts reckon Metrolink could switch to solar power to reduce pollution AND bring down fares.
The tram network is mostly run through the electrical grid. But climate and energy charity 10:10 has produced a report arguing the case for a semi-switch to solar power.
Despite Manchester’s reputation for grey skies, they reckon harnessing the power of the sun could slash £350,000 from Metrolink’s annual £7m electricity bill – and cut 13 per cent off carbon emissions.
Leo Murray, head of strategy at the charity, said: “Manchester isn’t India so you couldn’t fully charge Metrolink all-year round – but if Metrolink management suggest it’s not possible then I think they are just being pessimistic.”
Because of seasonal constraints, he says Metrolink could be almost entirely powered by the sun in summer – dropping to just 10pc in the winter – and still make the savings which could be passed on to passengers. Panels could be placed on brownfield sites and rooftops, although getting land permission could be a hurdle.
The study, authored by Mr Murray and Nathaniel Bottrell of Imperial College London, was originally commissioned to look at heavy rail systems but they realised it could also be applied to light rail.
Leo added: “Instead of paying a generator, this would allow Metrolink to bypass the grid. We’re hoping to go into this in more detail and have a conversation with Manchester transport leaders when we’ve carried out more detailed analysis of the scope.”
Parts of the Metrolink are already powered by solar and other renewable energy sources.
Danny Vaughan, Transport for Greater Manchester’s head of Metrolink, said: “We are acutely aware of the need to make all our public transport networks the greenest and cleanest they can be.
“Aside from walking and cycling, light rail is one of the most environmentally-friendly ways to travel and we’re proud of Metrolink’s green credentials.
“Certain components on Metrolink are already powered by solar, such as line-side track lubricators, but it is unlikely that solar power alone would be able to generate the necessary energy to run a light rail network of Metrolink’s size, with almost 100 trams operating at any one time on a 60-mile, 93-stop network. We will of course continue to explore ways to utilise new technology and renewable energy.”
